Email war

So in response to my latest ad I had a guy who was doing everything right - polite email, sent a face pic etc. I decided he fell way out of my four beers or less rule so I didn't reply. I just thought I didn't need to explain myself so I would just go silent. People do that to me all of the time and I'm sick of being super, super polite and explaining myself to everyone who can tap a keyboard.A
